Vendors continued to turn to flash memory in 2015, looking to deliver better performance. Enterprise storage systems that include flash have low latency, and if equipped with NAND flash, they can outperform hard disk drives and tape. Created in the 1980s, flash memory has proven to withstand the test of time, remaining one of our most-viewed data storage terms in 2015.

New approaches to flash memory arrive
Interest in data archiving should come as no surprise due to the rapid data growth seen in recent years. By moving data that is no longer active to a separate device, data archiving helps organizations deal with older data that needs to be protected, without exhausting primary storage resources.
Data archiving options for your organization
Data retention policy
Once data has been archived, data retention comes into play. A data retention policy refers to an organization's protocol for retaining information for operational or regulatory compliance purposes. Such a policy also allows organizations to organize information so it is easier to find and to determine when to dispose of unnecessary information.
Factors to consider when creating a data retention policy
Asynchronous replication showed up in a variety of storage products in 2015. While similar to synchronous replication, asynchronous writes data to the primary storage first, and then copies the data to the replica, while synchronous writes to both simultaneously.
Is asynchronous or synchronous replication best?
Software-based replication options
Data reduction techniques, such as compression and deduplication, assist in lowering data center costs. And this was especially relevant in 2015, with the increased interest in all-flash data centers. By eliminating redundant copies of data, data reduction increases efficiency and lowers storage costs.

Volume Shadow Copy Service-based backup
Volume Shadow Copy Service-based backup, or VSS-based backup, creates snapshots, called shadow copies. This service is provided by Windows, and is also known as Volume Snapshot Service (VSS). Enterprise backup software, such as VSS, has seen a growth in the market in recent years due to data capacity growth.

Many organizations are taking advantage of the cloud, which can lower costs, and boost scalability and backup for storage. A multi-tenant cloud allows customers to share computing resources in a public or private cloud. Each tenant's data is isolated and remains invisible to other tenants.

Crisis management plan
Having a proper crisis management plan (CMP) is vital to respond to critical situations that could negatively impact an organization. CMPs should detail various situations, including how to determine a crisis, early warning signals and procedures for responding to the crisis. Similar data storage terms include business continuity action plan and disaster recovery plan.

An enterprise solid-state drive (SSD) appeals to organizations because of its higher performance, consistent and persistent quality of service, and a greater level of endurance versus a standard client or consumer SSD. Enterprise SSDs also excel at handling I/O-intensive workloads.
Enterprise SSD options abound: What you should look for
Are SSDs and enterprise desktops a viable pairing?
If an application doesn't make frequent writes, a read-intensive SSD can be a valuable tool, because it can use less expensive types of NAND flash and doesn't demand the same level of endurance as write-intensive workloads.
